Question

which excerpt from neil degrasse tysons \death by black hole\ best provides evidence that escape from a black hole is impossible?
... the speed required to escape a black hole is greater than the speed of light itself. . . . light travels at exactly 299,792,458 meters per second in a vacuum and is the fastest stuff in the universe.
but if the black hole were 6,000 feet across, then the same mans feet would be only one - tenth of 1 percent closer to the center than his head, and the difference in gravity—the tidal force—would be correspondingly small.
meanwhile, the stuff within the event horizon has collapsed to an infinitesimal point at the black holes center. so black holes are not so much deadly objects as they are deadly regions of space.
if you stumbled upon a black hole and found yourself falling feet - first toward its center, then as you got closer, the black holes force of gravity would grow astronomically.

Explanation:

To determine which excerpt shows escape from a black hole is impossible, we analyze each option:

• The first option states the escape speed from a black hole is greater than light speed, and light is the fastest in the universe. Since nothing can exceed light speed, this shows escape is impossible.
• The second option discusses tidal forces based on black hole size, not escape impossibility.
• The third option describes the structure of a black hole (event horizon and center), not escape.
• The fourth option explains the increasing gravity as one falls into a black hole, not escape impossibility.

Answer:

... the speed required to escape a black hole is greater than the speed of light itself. . . . light travels at exactly 299,792,458 meters per second in a vacuum and is the fastest stuff in the universe.
